Plant Profile: Boltonia asteroides

False chamomile is a perennial member of the daisy family, commonly found in roadside ditches, marshes, and other moist environments across the eastern United States. Its species name, "asteroides," derives from Latin, meaning "resembling asters."

For optimal growth, this plant should be placed in full sunlight and well-drained soil. When grown in wet conditions, it may require staking due to its tendency to flop over. Conversely, if planted in drier soils, the plants will be shorter and produce less vibrant flowers. To encourage a more compact growth habit, trim the stems back in the spring before flowering begins.

The flowers typically feature white petals surrounding a dome-shaped yellow center, although some variations may display pink-tinged or violet rays. Blooming can occur from late summer until the first frost. This plant propagates through creeping rhizomes or by seed dispersal.

False chamomile is an excellent choice for cottage gardens, cutting gardens, or as a backdrop in borders, where its bright green leaves can provide a striking contrast to its grayish foliage. It is also tolerant of clay soils.

In terms of pests and diseases, this plant does not face significant threats, although powdery mildew can occasionally be a concern. It can become somewhat weedy, so opting for cultivars like 'Snowbank,' which are more compact and less invasive, may be beneficial. Staking may still be necessary for some plants.
